Gingrich’s main rival for the non-Romney vote, former senator Rick Santorum (R-Ga.), is planning a visit to Georgia this weekend. In the meantime, Santorum is spending his Friday in two other big states – Michigan (where polls show him in a competitive race against Romney) and Ohio (where we’ll catch up with him later today).

Romney and Rep. Ron Paul (R-Texas) are spending the day in Idaho – a state that got little love from the candidates four years ago when its primary took place in May, but that this year is seeing a flurry of visits thanks to its Super Tuesday caucus.
